Phosphorodiamidate morpholino oligomers (PMOs) are uncharged DNA analogues that can inhibit bacterial growth by a gene-specific, antisense mechanism. Attaching cationic peptides to PMOs enables efficient penetration through the Gram-negative outer membrane. We hypothesized that cationic groups attached directly to the PMO would obviate the need to attach peptides.
